Article Abstract
Ischemia/reperfusion (I/R) is one of the major causes of acute kidney injury (AKI) and associated with increased mortality and progression to chronic kidney injury (CKI). Molecular mechanisms underlying I/R injury involve the production and excessive accumulation of reactive oxygen species (ROS). Peroxiredoxin (Prx) V, a cysteine-dependent peroxidase, is located in the cytosol, mitochondria, and peroxisome and has an intensive ROS scavenging activity. Therefore, we focused on the role of Prx V during I/R-induced AKI using Prx V knockout (KO) mice. Ablation of Prx V augmented tubular damage, apoptosis, and declined renal function. Prx V deletion also showed higher susceptibility to I/R injury with increased markers for oxidative stress, ER stress, and inflammation in the kidney. Overall, these results demonstrate that Prx V protects the kidneys against I/R-induced injury.

Extracorporeal blood purification (EBP) is an emerging technique for reducing elevated levels of inflammatory mediators and/or endotoxins in critically ill patients with sepsis or other hyperinflammatory conditions. The oXiris filter combines endotoxin adsorption, cytokine adsorption, hemofiltration and anti-thrombosis, and an emerging body of evidence demonstrates its use in critical care patients with hyperinflammatory conditions and acute kidney injury (AKI). A group of Asia-Pacific experts convened to formulate consensus statements for the use of the oXiris filter based on a comprehensive review of publications.

Sodium-glucose co-transporter 2 inhibitors (SGLT2i) are a fairly new class of agents for diabetes that have demonstrated significant benefits in glycemic control and cardiovascular outcomes with outpatient use. The aim of this review is to provide an overview of the effect of SGLT2i use on glycemic control and clinical outcomes in the hospital setting.An electronic search of PubMed was conducted to analyze publications that assessed the inpatient use of SGLT2i and included patients with diabetes.

Objective: This meta-analysis aimed to compare the perioperative safety and efficacy of transcatheter aortic valve replacement (TAVR) versus surgical aortic valve replacement (SAVR) in bicuspid aortic valve (BAV) stenosis.
Methods: We systematically analyzed studies from PubMed, Cochrane Library, Embase, and CNKI comparing TAVR and SAVR in BAV stenosis. Outcomes included postoperative mortality, complications, all-cause survival, and freedom from stroke.
